We present a case of infectious myositis of the iliacus muscle in a child, diagnosed clinically and radiologically. The Iliacus joins with the Psoas Major to form the Iliopsoas. The iliacus is a large, flat and triangular shaped muscle that fills the It proceeds across the iliopubic eminence through the muscular lacuna to its insertion on the lesser trochanter of the femur. Look no further than these 3D muscle videos. Its fibers are often inserted in front of those of the psoas major and extend distally over the lesser trochanter. insertion. The medial muscles of the hip joint that insert on the linea aspera are the _____. Iliacus Muscle. The psoas major unites with the iliacus at the level of the inguinal ligament and crosses the hip joint to insert on the lesser trochanter of the femur.

Variations with the iliacus and psoas muscles have been previously reported in the literature; however, to the authors’ knowledge, none have been reported identical to the current case. Muscle anatomy of the iliopsoas includes origin, insertion, action, innervation and vascular supply. The iliopsoas muscle (the muscle formed by the combination of the iliacus and psoas major muscle ) then attaches to the lesser trochanter of the femur. * If you have a disc bulge, herniation, or sciatica, try the modification instead.
